, JEJJE A. H/JA 5E Patented Aug. 15, 1944 UNITED STATES PATENT OFFICETheA present invention relates to improvements in baling machinesprimarily adapted for baling hay. straw, and like material.

One of the objects of` the present invention is to provide a balerwhich, during the formation of the |bale, will automatically embrace thebale with binding wires and, upon the completion of the bale, willautomatically tie the wires before the bale is delivered from themachine.

Another object of my invention is to provide an improved bale wire tyingmachine which fautomatically will tie the free ends of the binding wireor wires which have been passedaround the bale and upon the completionof the tie, sever the tied wires from the source of Supply.

For the purpose o f disclosing my invention, I have illustrated anembodiment thereof in the accompanyingdrawings, in which:

In the embodiment of the invention illustrated,

formed of a plurality of spaced apart side `panels or bars 2. These barsor panels 2 are suiiciently spaced4 apart vertically to provideinterstices 3 therebetween, which permit the passage there- 5 through ofthe baling wire and the bale wire needles.

The baling chamber likewise is provided with a top and bottom, whereby asubstantially closed chamber is provided into which the material to bebaled, is fed. Preferably the side membersl 2, aswell as, if desired,the tops and bottoms, are

provided with inturned forwardly inclined spurs I which, whilepermitting the passage of the material to be baled forwardly, will actas a preventer means for restraining the backward movement of thematerial after it has once been pushed forward into the chamber. Thematerial is compressed in the vbaling, chamber I through the medium of abaling plunger` 5 driven from a suitable reciprocating plunger 6operated from the main drive wheels l. which in turn are driven by anysuitablej'means, such as a gasoline iengine or other power deliverydevice. The material is delivered into the baling chamber I from aprecompresslon chamber B into which the material may be fed by anysuitable means through a suitable side opening, rearwardly facthe supplyof, material in the precompression chamber from the source of supplybefore it is fed into the baling chamber.

In order lto automatically bind the bale, as it is bing formed, with abinding wire, I provide a 40 means whereby aplurality of strands ofwire,

in the present instance three, are initially stretched across thelbaling chamber in advance of the feeding of material therein. Thesewires are gripped' on the far side of l the chamber and, as the materialis pushed lforward in the formation of the bale, the wire automaticallyfeeds forward with the material from the near" side of the machine, thussurrounding the bale with thebinding Wires as the bale is formed. Tothis end, Ivprovidea plurality of wire grippers, kthree in number, andas each of the wire grippers and'its cooperating wire tie and needle areof the same construction, a description of one set of these parts willbe sufficient.

On the far side of the baling chamber, (see Figs. 1, 2, and 3) there isprovided an oscillating frame comprising a vertical supporting rod l0connected Vat its top and bottom to oscillating levers ll pivoted at I2on stub shafts mounted there is provided a baling chamber l, preferablyon the top and bottom of the compression cham- `(See Fig. 13).

ber.. The lever II is provided with a driving sprocket I3 by which theentire frame, including the vertical bar I0, may be oscillated. Thisvertical bar I carries the wire gripper (see Figs. 3 and 9) comprising adisc or roller I4 suitably mounted on an arm I5 extending from the barI0. This disc is preferably grooved to receive the wire and mountedabove the disc is a guide member I6 which is provided at one side with adownturned spur I'I and on the other side with an upturned spur I8. Thisguide member is provided with a stud I9 which passes through the disc I4and the support I5 to holdthe parts in their assembled position and toprovide a journal mounting for the element I4. Cooperating with thisgripper disc I4 is a gripper dog 20 pivoted on a stud 2I on a lip 22 ofthe support I5 and offset from the disc I4. The free end of this dog isbiased in a direction to engage the wire upon the periphery of the discI4 and to this end, the pivot stud 2I is provided with an arm 23 havingsecured to one end thereof a biasing spring 24, the opposite end ofwhich is anchored on the support I5.

As will be seen from an inspection of Figs. 1 and 3, the wire, which maybe fed from a supply spool (not shown) is wrapped about a tension drum26 for a purpose which -will appear hereinafter, andthence is threadedthrough a needle 25 and over a roller 2l at the end of said needle. Fromthe needle end, the wire extends across the baling chamber to thegripper assembly, being bent about one of the two posts 42' and thenceextending around the disc I4 beneath the guide I6, where it is engagedby the dog 2U in such fashion as to' prevent movement of the wire in aclockwise direction with respect to the element I6 as viewed in Fig. 3.This condition of the parts is indicated in Fig. 15.

Associated with each wire gripper is a tie mechanism comprising a frame,(see Figs. 3, 11 and 12) side members 28 and on which the twisters 29and 30 rotate. These twisters are driven by a gear 3I keyed on a shaft312 which extends parallel with the baling chamber 2 and is driven froma driving mechanism 33 to be more fully herein- .after described.

The frame 28 is keyed on a sleeve 34 surrounding the shaft 32 and thisframe is rotated from the driving mechanism 33 in a manner hereinaftermore fullydescribed.

Located on either side of the frame are wireholders 35 and 36 in theshape of side bars bolted to the frame and the -bar 36 is provided atits ends with slots or throats 3l adapted to coincide with the slots 30in the twisters 29 and 30. The bar 35 likewise has a `pair of throats 38in its opposite endsywhich also coincide with the slots 3U' respectivelyin the twisters. These coinciding slots flare yradially outwardly, asshown in Figs. 1l and 12, but near the a-xes of the twisters 29 and 39,they are all of just sufficient width to receive a single wire so thatwhen a plurality of wires are laid in these slots, they lie in parallelside-by-side relation, upon'a common radius of the associated twister.Therefore, when a pair of wires are lying in the stationary throats ofthe holders 35 and 36 and in one of the twisters, a

rotation of the twister will twist the wires about one another toeffectually tie these two wires together.

The sleeve 34 housing the shaft 32 is rotatably mounted in a bearing 4Icarried by a bracket 42 mounted on the side of the baling chamber. Thisbracket has formed thereon a stationary cutter blade 43 and mounted onthe rotatable sleeve 34 to rotate therewith is a revolving cutter blade44 having a pair of cutting edges 45 and 45.

With the parts in the positions of Fig. 15, feed of material by thebaling plunger will form a baleembracing bight in the wire, asillustrated in Fig. 16, with one strand ofthe wire extendingsubstantially parallel to the line of bale movement on the near side ofthe chamber, a second strand 25" extending across the chamber in frontof the bale, and a third strand 25 extending rearwardly along the farside of the bale adjacent kthe tie mechanism.` This strand 25"' loopsover "the posts 42 and extends forwardly to provide a strand 254,the'free end or' which is held by mechanism, and that the upper surfaceof the adjacent bar 2 of the baling chamber also lies substantially inthat horizontal plane. Because of these facts, the strand 256 ofthewire, which is supported upon said bar surface, engages the post 42' ata point lying substantially in the Ihorizontal plane of the said mouthof the tie mechanism. The strand 254 leads, as is clearly shown in Figs.3 and 9, from that point of engagement with the post 42 of the gripper,whence it extends beneath the guide member I8 and around the roller I4,being engaged between said roller and the dog zo.

At substantially the same time that the needle 25 is moved across thebaling chamber to form the loop comprising the strands 255 and 256, theframe consisting of the upright I0 and the arm I I is swung toward therear of the baling chamber. Thus the strand 254is swung substantiallyabout its stationary lpoint at which it engages the post 42.', andthrough an angle somewhat greater than 180 degrees, in a substantiallyhorizontal plane. Because of the relative positions of the substantiallystationary point of the strand 254 and the outwardly presented mouth ofthe tie mechanism, this movement oi the gripper lays a Iportion of thestrand 2li4 in that outwardly [presented mouth of the tie mechanism.When the wire is laid in the twister slot it will have passed beneaththe end of the locking lever 4l shown in Figs. 14 and 3. This lever ispivoted as at 46 on the side of the frame and biased into lockingposition by a coiled spring 49 all shown in Fig. 3.

The wire now being held in the free end of the slot and gripped by lever41, the arm 50 on lever 23 (see Fig. 9) will strike a stop member 5Imechanism, the taut wire, engaging the post 42', as it does, in theplane of that mouth, will be laid in that mouth as the frame swings fromthe position illustrated in Fig. 3 to the opposite limit of itsmovement.

As the frame reaches thatopposite limit of its movement, the guide I6will engage beneath the loop comprising the strands 255 and 256, thespur I1 guiding the wire up over therupper surface of the guide I6, andthe frame moving far enough so that the loop will slip over the spur I6.This condition of the parts is indicated in Fig. 1'1.

As the upright I?) and its associated parts now starts to return towardthe position illustrated in Fig. 3, the strand 255 will lie beneath theguide I6, while the strand 255 will lie upon the upper surface I6 of theguide I6. As the parts swing in a counter-clockwise direction `from theposition of Fig. 17, the wire will slide with respect to the gripper,and the strand 255 will slip down across the sloping surface I6' andinto the groove of the roller Iii. Likewise, this movement of the partscarries the ringer 23 away from the stop 5I to permit the dog 20 to moveinto contact with the wire. It will be clear, however, from aninspection of Fig. 3, that the dog will not operate to resist movementof the wire relative to the disc I6 in a counterclockwise direction, butwill prevent relative movement in a clockwise direction.

Thus, as the upright IIJ swings from the position of Fig. 17 toward theposition oi' Fig. 18, the gripiper slides along the wire strand 255,while drawing the strand 255 through the needle 25.

By the projection of the `needle 25 from the position of Fig. 16 to the.position of Fig. 17, the strand 255 has been pulled tightly across thebaling chamber, bending about the near" trailing corner of the bale. Thepoint at which the wire is bentwill, of course, lie in the horizontalplane occupied by the free end of the needle when the needle is in itsretracted position of Figs. 1 and 15.

- The strand 255 will lie substantially in that plane throughout itslength, even while a portion thereof lies on the upper surface I6' ofthe guide member I6; and of course when the strand 255 drops into thegroove of the roller I4, the whole strand lies substantially in theplane previously occupied by the strand 254. Itis to be noted that, asthe frame swings, toward the position of Fig. 3, the guide member IBmoves through a path considerably spaced from the outwardly openingmouth of the tie mechanism. Thus the strand 255 is carried along theupper surface ci said bar 2, which further tends to establish thehorizontal position of the body of the strand 255 substantially in theplane of the open mouth of the tie mechanism; and therefore the strand2551s laid in that mouth as the frame approaches the position ot' Fig.3.

'Ihe strand 25,as it is pulled through the needle by movement of theframe and gripper toward y shown in Fig. 19.'-v Thls wire portionreadily rides beneath the tie mechanism because of its tendency to droopsomewhat of its own weight whiley standing out in the position of Fig.18.

Suitable mechanism later to be described now drives the shaft 32 to spinthe twister 30to twist together the strands l254 and 255. As thattwist-4 ing is completed, the sleeve .34 is rotated, whereby the knie M iscaused to sever the'strand 255, and the tie mechanism side members 28are rotated through 180 degrees, whereby the stationary cam 52 will becaused to force the tied strands out of the twister mouth, and the mouthof the twister element '29 is brought into position to receive the wirestrands for the next cycle of operation. The parts now stand in thecondition illustrated in Fig. 20, and the completed bale is moved on asa new bale is started by material forced into engagement with the strand256.

Each of the needles is carried, atits :rear end, ons. reciprocatingframe 53 and is guided at its forward end through a suitable guidemember 54. A coiled spring 55, surrounding each of the needles andbearing on the guide member 54', biases the needles and their frame 53toward a retracted position. The frame is moved to move the needles to aprojected position through the medium of a drive mechanism comprising areciprocating plunger 56 connected through the medium of a cable 51 withthe frame 53. This plunger is slidably mounted in a pivoted guide 53pivoted at 59 on one side of the baling machine, and the plunger 55 isprovided with an upturned hook 60. A second reciprocating plunger 5I isconnected` by a connecting rod 62 with a Y crank 63 on one of the shaftsof the drive wheels 1 so that, as the drive wheels rotate, this crank 52will operate the reciprocating plunger 6 I. This plunger 5I is providedwith a downturned hook 64 sc arranged that when the end of the plunger56 is in its raised position, the hook 66 will enga-Sethe hook 60, tomove the plunger 56 to the v left, looking at Fig. thusy shifting theneedles y to carry the baling wire across the baling chamber.

' drum 26. It is to be remembered :that the wire the position of Fig. 3,tends to follow the curved path of the gripper. Thus, the stift, curvedstrand 255, lying upon the side of the roller I4 opposite the strand255, is carried outwardly Ibeyond the position of the tie mechanism, andas the frame moves past its position in which the arms II areperpendicular to the adjacent side of the baling the hooks 60 and 6,4 toengage at the periodA when the bale is completed and the baling plunger5 is moving to its retracted position.` It is to be noted that with .themovement of the baling plunger to its retracted position, the plunger5I, and with it the plunger 56, will be moved to the left, looking atFig.y 2, thus projectingthe needles across the baling chamber as thebaling plunger is retracted.

The sprocket I3, which is driven to oscillate the frame comprising thevertical rod I and the levers I, is driven through the medium of a chain1| which connects the sprocket |3 with a driving sprocket 12. Thisdriving sprocket is oscillated by a crank arm 13 pivotally connected at14 with one end of a link 15 having its other end connected as at 16with the frame 53. Therefore, as the frame 53 is reciprocated to projectthe needles forward and Y backward across the baling chamber, the framecarrying the grippers for the free end of the wire is oscillated toswing ,the free end of the wire into the tie and pick up another portionof the wire to carry forward again.

The drive mechanism for the sleeve 34 and the shaft 32 comprises twosets of Geneva gears, (see Figs. 3 to 8) one set comprising the drivinggear 11 and the driven gear 18, the driven gear being keyed to the shaft32. The position of these gears, when the tie is completed and the partsare ready for a new tie is illustrated in Fig. 4. The second set ofdriving gears consists of the driving gear 19 and the driven gear 80which driven gear is keyed to the sleeve 34; and when the gears 11 and18 are in the positions illustrated in Fig. 4, these gears 19 and 30will be in the positions illustrated in Fig. 5. By the time the wireshave been laid in the tie throats and at the beginning of the twistingaction, the gears 11 and 18 will assume the positions illustrated inFig. 6, while the gears 19 and 80 will'be in the positions illustratedin Fig. '7; and after the tie is completed and the tie mechanism isbeing turned to throw the tie wiresl out of the tie mechanism, the gears19 and 80 will be in the positions illustrated in Fig. 8. The two gears11 and 19 are driven from a shaft 19' which in turn is driven, through asingle-revolution clutch of standard construction (not shown) tripped bybale growth in a manner well understood in the art, from asuitablerbevel gearing train (see Fig. 2) indicated generally at 8| anddriven from the shaft 82 of the driving motor, which motor is not onlyadapted to drive this shaft but may also drive the baling mechanism.

In Fig. 22, I have illustrated a modified form of the needle forthreading the baling wire across the baling cham-ber. In the structureillustrated in Fig. 1, the needle reciprocates with a rightline movementacross the baling chamber. In

I I6 are arcuate in shape and are mounted at one end of an oscillatingarm |I1 pivoted at ||8 on a shaft extending upwardly fromthe top of thebaling chamber. These needles, at their feeding on the arm l5 a disc I2Isimilar in structure and function to the disc I4 shown in Fig. 9'. Abovethis disc is a guide member |22 similar to the guide member I6 andhaving the upturned guide finger |23 and the downturned guide finger|24. Associated with the upturned guide finger |23 is an overhangingfinger |25 carried by the arm I5, slightly spaced from the guide member|22, and so arranged that as the arm I5 swings from the full lineposition to the dotted line position (Fig. 22), the guide finger |24vwill pass beneath the wire, causing the same to Slide up over the guidefinger |23 and down in front of the finger |25. As the arm I5 swingsback toward its full line position, the wire will be bent around the endpost |24 on the arm I5 and due to the holding action of the finger |25,the wire will be kinked suiliciently to be firmly gripped by the grippermechanism shown in Fig. 23 and pulled through the b alng chamber andlaid in the tie mechanism.

As the wire is swung with the arm I5, the arm moving from the full lineposition to the dotted line position and held by the gripper of the typeillustrated in Fig. 23, the strand of wireis laid on an arm |21extending beyond aplate |28 provided with an upturned flange |29 bywhich said -plate may be secured to the side of the baling chamber.Overhanging the arcuate arm |21 is a plurality of upwardly inclinedresilient fingers |30 having downturned ends I3| and as the wire is laidon the arm |21, it passes beneath the spring fingers |30. The end |32 ofthe plate or arm |21 is upturned so that as the arm I5 swings back toits normal position after having laid the initial strand in the tiemember, the wire will pass beneath the plate |32 forming a loop andlaying the second strand of the loop in the tie member, substantially asis done in the structure illustrated in Fig. 3.

The structure illustrated in Fig. 24 takes the place of the -holderillustrated in Fig. 14 and accomplishes the same result, whiledispensing with a number of moving parts.

The present application is a continuation in part of my applicationfiled July 3, 1940, Serial the structure illustrated in Fig. 22, theneedles ends, are lprovided with rollers I I9 over which the wires fromthe feeding spools are adapted to pass. The arm ||1 is oscillatedthrough the medium of a driving chain |20 in one direction and returnedto its retracted position through the medium of a coiled spring |20having one end fas-- tened to the arm II1 and the opposite end anchoredon the baling chamber. In this arrangement, the needles ||6 in theirretracted position lie somewhat parallel to the side wall 2' of thebaling chamber and as the arm ||1 is swung, the needles IIS are swung inan arc from the position shown in full lines in Fig. 22 to the positionillustrated in dotted lines in said figure, feeding the baling wiresacross the baling chamber in the same manner as does the needle 25 inthe structure illustrated in Fig. 1.
